,FIRE-EXTINGUIsHEE A To all whom t may concern:

Be it known that I, FRANK SIMONE, a citizen of the United States, 'residing at New York, in the county of New York and State of New York, have invented'new and` useful Improvements in Fire-Extinguishers, of which the following is a specification.

This invention relates to {ire-extinguishers, and the main objects`of the same are to provide a new andnovel arrangement of the pumping mechanism including a slidable casing for the piston; to provide an improved arrangement of floating valves in conjunction with the pumping mechanism whereby to enable the fluid to be drawn from the lowermost point of the container, irrespective of whether the extinguisher is inclined upwardly or downwardly; to provide an improved arrangement of the pumping mechanism andi lcoperating Heating valve mechanism so that the same may revolve together on an axis, permitting the floating valve mechanism to fall alwaysby gravity to the lower side of the container; and to provide a novel insertion-extension so that containers made in larger size, may

employ. the same standardized pumpingv mechanism and ioating valve mechanism.l

With the foregoing and other objects in view, which willbecome more apparent as the description progresses, the invention resides'in the construction, combination andl arrangement of parts hereinafter described and shown in the accompanying drawings, rforming a material part of this specification, and in which Figure 1` is a view in perspective of the exterior of lmy fire-extinguisher.

My improved fire-extinguisher yembodies an outside casing 15, which is made preferably cylindrical in form, although other forms may be employed with goodresults. This casing is made to form part of a container by securing to the front and rear ends thereof, the caps or end closures 16 and 17, respectively. These formed preferably with outwardly projectcaps areV ing ianges (Fig.'2), which engageliqu1dtight the inner periphery of the casing 15,

formed with the front cap 16 is a nozzle 18 having a shouldered'and reduced inner end 19, the nozzle being provided with asuitable liquid discharging aperture 20. j'

With the rear cap 17 is formed acentral hub portion or bushing 21 having an outside iange 22, into -which is fitted an outer cap plate 23 having a central opening 21 of. alined radial slots 25. The hub portion v21 is also provided with a circular opening 26 concentric With the opening 24 but of smaller diameter. y

Revolubly mounted upon the 'reduced portion of the nozzle 18 is a fitting 27 formed` Centrally therethrough in communication with a pair Y Threaded into the {iange of the fitting 30 p at one end, and rigidly secured tothe inner face of the tting 27 at the other end, is a cylindrical casing 32 which isA provided at its front end vwith the ports or apertures 33 and 34, located in different transverse planes and also at the rear end with parts 35 and 36 similarly located.

Slidably fitted withinthe casing 32 is a' casing 37, the ends of which are open, and' -which is shorter inl length than the casing n 32 and having Provided 9D,` the Same side p thereof adjacent its front and rear ends, the

ports or apertures 38 and 39, respectively. The length of the slidable casing 37 is such that when it clears the port 33, the port 35 at the rear .end will be closed, vand conversely. It should also be noticed here that when the port 33 is cleared, communication between the ports 34 and 38 is closed, while that between the ports 36 and 39 is open and conversely, that when communication between the ports 34 and 38 is opened with the opening of port 35, the ports 36 and 39 are closed. In order to enable the inner ca sing 37 to slide without turning, it is provided at its front end, with a longitudinal s lot 40, in which is entered a pin 41, rigid with the outer casing. I

Reciprocable withinthe inner casing 37, and through the openings 2.6 and 24, is a piston rod 42 having a piston head 43, which yis in such tight engagement with the inner casing 37 that when the piston rod is moved, the inner casing is also moved accordingly to the full extent to which its length permits, the piston beingcapable of further movement after the' casing is brought to rest, the purpose of which is to open and close the openings as hereinbefoi' described.

Fastened at one end of the piston head 43 so as to project centrallv in advance of the same, is a coil spring 44 carrying a cup member 45 adapted to engage the head of the vpin 46 which slidably pierces the rear wall of the ltting 27, the said pin rigidly carrying in advance of said wall, a cup member 47, which is designed to engage the discharge aperture 20 of the nozzle,vclosing the same against the passage of fluid, when the piston' is locked against movement. j spring element 48,A carried upon the piii 46, is designed to normally maintain the cup 47 out of engagement with-tlie nozzle for the passage of fluid. Thus I arrange for the opening of the nozzle for the discharge of the iiuid by the retraction of the piston rod, the outside end of said rod being provided with a cap-fitting 49 having a cavity on its inner side for retaining packing as 50, and also having outwardly projecting lugs adapted to snugly engage the underside of the cap plate 23 by the turning of the key 7 handle 51.

' pipe 53 which is in communication with the ports 33 and 35 by means of the pipes 54 and 55-frespectively. Fitted upon the opposed ends'of thelsuction pipe 53 are valve housings 56 and 57, each having an orifice opening toward the corner produced by the union of the exterior vcasing with the end cap. Extending through the suction pipe is a rod 58 which is provided with the guide members 59 and 60, the opposite ends of said rod being equipped With the oating valves 61 and 62 adapted to seat against the endsof the suction tube to close communication therewith, the said valves being so spaced that when one opening is closed the other will be open. While, in order to permit the passage of the fluid through the suction pipe 53, I prefer to employ the form of guide-members as 59 and 60, as indicated in Figs 2 and 6, yet the modilied form 59'., illustrated in Fig. 7 also permits the passage of the fluid and brings about good results.

In Fig. 5, I illustrate the means by which I can produce a larger container to hold a before. The cylinder-like member 64 is pro- I 'vided with a plurality of apertures as 65 to enable the liquid to enter the saine, thereby utilizing all space available in the container. Under this construction too, instead of attaching a valve housing as 56 to the front end of the suction pipe 53, I attach a housing 66 having, preferably integral therewith, a tube 67, which opens as before into the corner produced by the union of the casing l5 with the end cap 16, whereby to suck the liquid from the lowest point.l

The cap 1.7 is provided with a ller opening 68, which is held normally closed by means of' a spring actuated plug 69, the spring being seated upon an inserted bushing 70, whereby to hold the disk valve 71 tight against the bushing. As bestl illustrated in F ig. 10, the projecting end of bushing 70 is formed with exterior ribs 72,

vupon which rests a cap 73 so as to provide sector-like spaces between the exterior of the bushing 70 and the interior side of the cap 73 for the admission of air, When the air pressure within. the container is less than v that of the outside atmosphere, it being observed in this connection that the tension of the spring 69 is merely sufficient to maintain the disk 71 tight against the bushing when the air pressure within the container is substantially equal to that of the outside v atmosphere.

The operation of my improved fire-'exi tinguisher is as follows: By turning the han;

dle 51, the cap 49 is released from the retaining plate 23, which operation allows the piston to be reciprocated in the slidable cylinder. As the piston is drawn upwardly the slidable cylinder is drawn with it until stopped by the fitting 30, thus enabling the liquid to pass through the ports 33 and 39, and preventing its passage through the ports .35 and 38 as hereinbefore described. Simuland port 38 is opened, and also port 39 is closed and port 35 opened, so that the liquid is forced from ythe cavity in' advance of the piston out through the nozzle, while into the cavity behind the piston the liquid is drawn by suction fromthe suction pipe 53. When the extinguisher is inclined. upwardly, the operation is substantially the same except 4that the `ioating valve 56 is closed while floating valve 57 is opened, thisk action being accomplished by gravity. l
